Answer:
My Volleyball season experience
As I had been getting ready for my second year of Volleyball tryouts my heart was pumping so fast in my chest I honestly thought I had been having a heart attack. Tomorrow was going to be the first day of tryouts and I was so excited yet nervous. Annika(my best friend) and I were practicing with our Volleyballs outside of her house. We were doing most of the drills we had remembered from the season before. After a couple of hours we decided we should stop before we pull a muscle or injury our bodies and rest up for tomorrow. My mother had cooked me up a grilled cheese sandwich with tomato soup, my absolute favorite meal ever, to get me ecstatic for tryouts and to settle my butterflies. Once I finished my delicious meal and proceed to get ready for bed, Annika and I called each other and talked for a while about what we were going to do tomorrow and how we hoped we would get on the team again. I quickly dozed off shortly after we hung up.
Answer:
The estimate of a population proportion is approximately 541.
Step-by-step explanation:
We can solve the the problem by using the formula for minimum sample needed for interval estimate of a population proportion which is given by the formula
n = pq ((Z/2) / E)^2
As, p is not defined so we use the standard p and q which is 0.5 and 0.5.
The reason for this is we have to choose form 0.1 to 0.9 both values of p and q, we will find the maximum value of pq occurs when they both are 0.5.
Next, we will find the value of (Z/2) by looking at the Z-table, we will find that at 98% confidence (Z/2) = 2.326. Now we start substituting the values in the above formula
n = (0.5)×(0.5) × (2.326/0.05)^2
n = 541.027
n ≅ 541.
No it is not. that is a right scalene triangle. Acute triangle has three angles less than 90.
